And the winner is...

...the satellite image of the Canary Islands.
NASA Earth Observatory comments the win:
''The second annual Tournament: Earth has come to an end, and the winner is a familiar face. In 2013, a submarine volcano off of the Canary Islands took the first championship. This year, the entire island chain got in on the action. ”Trailing the Canaries,” the #2 seed in the art bracket, romped through the tournament in 2014. The image showed interesting wind and wave patterns in sunglint on the lee side of the islands. The Canary Islands have a lot of fans!''

Canary Islands won again - cast your final vote now !

NASA Earth Observatory have  just released the results of last week's round of voting and the image the Canary Islands has won again to enter the final. Nasa writes:
''Last year, a longshot image showing an underwater volcanic eruption near the Canary Islands came from nowhere to win our first-ever Tournament Earth. The championship round of the 2014 tournament has arrived, and yet another Canary Islands image seems poised to capture the crown. However, “Trailing the Canaries” will have some stiff competition in “Activity at Kliuchevskoi,” a spectacular shot of ash streaming from one of the highest and most active volcanos on the Kamchatka peninsula. Vote for your favorite by Friday at 4 p.m. EDT / 8 p.m. UTC.''

Vote for the Canary Islands !

Last year a satellite image of the El Hierro eruption won the NASA Earth Tournament and became image of the year. This year's competition has entered the finals and again a beautiful image of the Canary Islands called Trailing the Canaries (below) has made it into the final eight - so do your bit and give it your vote. You must select four of the eight images according to your preferences and the image of the Canaries is in the art section. Voting closes tomorrow night, but you can vote as often as you like after clicking: NASA Earth Tournament 2014.  
UPDATE: This round was won and now see the next round of voting
NASA writes: ''The play of light on water can reveal overlooked details and nuances to photographers and artists on Earth. The same thing can happen when looking from space.The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite looked down on the Canary Islands on June 15, 2013. The Atlantic Ocean has a silvery or milky color in much of the image, the result of sunglint. Sunlight is being reflected off of the ocean surface directly back at the satellite imager, revealing details about the water surface or circulation that are otherwise invisible.   
In the image above, wavy, windsock-like tails stretch to the southwest from each of the islands. The patterns are likely the result of winds roughening or smoothing the water surface in different places. Prevailing winds in the area come from the northeast, and the rocky, volcanic islands create a sort of wind shadow—blocking, slowing, and redirecting the air flow. That wind, or lack of it, piles up waves and choppy water in some places and calms the surface in others, changing how light is reflected. Ocean currents, oil or pollution slicks, and internal waves can also alter surface patterns, though none are necessarily visible in this image.
According to sailors’ guides to the area, winds on the leeward side of the Canary Islands often blow in the opposite direction of the prevailing winds. The play of land and wind can also create a funnel effect, speeding up air flow around the coasts. The swirling nature of the leeward wind field is shown in a long, helical trail of clouds stretching southwest from Tenerife (the second island from the right).''
